Specification of Letters Patent.

Patented May 19, 1908.

Application filed August 28, 1907. Serial No. 890,424.

T 0 all whom it may concern:

Be it known that I, EDWARD LOOKYER, a citizen of the United States ofAmerica, residing at McKeesport, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful ImprovementsinWrenches, of which the following is a specification, reference beinghad therein to the accompanying drawing.

This invention relates to wrenches, and its object is, to provide adevice of this character, capable of being readily adjusted, and whichmay be employed as a hammer.

The improvement consists of the combination with a shank provided with afixed jaw, of a movable jaw slidably supported upon the shank, and meansfor locking said movable jaw to prevent its movement when the Wrench isto be used.

The construction of the improvement will be fully described hereinafter,in connection with the accompanying drawing, which forms a part of thisspecification, and its novel features will be set forth in the appendedclaims.

In the drawing, Figure 1 is a side elevation of a wrench embodying theinvention, Fig. 2 is a front elevation of the same, Fig. 3 is a rearelevation of the im roved wrench, Fig. 4 is a side elevation part ybroken away, and Fig. 5 is a section on the line 0cac of Fig. 1.

The reference numeral 1 designates the shank of the wrench provided withteeth 2, and a fixed jaw 3. Slidably supported upon the shank 1 is amovable jaw 4, provided with a loop 5 embracing the shank. The jaw 4 islongitudinally recessed to receive a toothed dog 7, to the oppositesides of which are secured parallel arms 8 by means of pins 9.

- The dog 7 is connected to the movable jaw 4 by a cross pin 10,extending through an elongated slot 11 formed in the dog 7. A pin 12connects therear ends of the arms 8, andupon said pin is mounted aneccentric 13 having a depending arm or lever 14, to which is pivotallysecured a latch 15, rounded at its free end to adapt it to engage anotch 16 formed in one of the arms 8.

The utility and operation of the device constructed as thus described,will be readily understood. When the dog 7 of the movable jaw 4 isreleased from its engagement with the toothed shank 1 by turning the arm14 to the position shown in Fig. 4, said jaw 4 may be readily adjustedwith relation to the fixed jaw 3, after which said movable jaw is lockedin its adjusted position by turning the eccentric to the position shownin Fig. 1.

When it is desired to use the wrench as a hammer, without looseningthejaw 4, the latch 15 is turned u on its pivot to engage the notch 16.Thes 0t 11 in the locking dog permits of the required movement of saiddog, and the parallel arms 8 secured thereto. When the wrench is inaction the lower aw thereof is not tight to the shank but works ratherloosely to give itself relief from the work.

I will have it understood that the invention includes all suchmodifications and variations in the details of construction as may fallwithin the terms and scope of the following claims.

Having now described my invention what I claim as new, is

A wrench comprising a toothed shank provided with a fixed jaw, a 'awslidably supported on said shank and longitudinally recessed, a tootheddog, arranged within the recess of the sliding aw and loosely connectedto said sliding jaw, parallel arms secured at their forward ends toopposite sides of said dog and connected at their rear ends by a crosspin, an eccentric mounted on said cross pin and provided with an arm orlever, and means for locking the eccentric arm, consisting of a latchpivotally connected to said arm and adapted to engage a notch in one ofsaid parallel arms.

In testimony whereof I aflix my signature in the presence of twowitnesses.

EDWARD LOCKYER.
